This invention relates to new and useful improvements in sprinklers andthe primary object of Vthe present invention is to provide a sprinklerincluding novel and improved means for selectively discharging a iluidfrom the same in the form of any desired segment of a circle.

Another important object of the present invention is to provide a lawnsprinkler includ-ing a stand and novel andimproved means for pivotallyadjusting the sprinkler at selected positions relative to the stand.

A further object of the present invention is to provide a lawn sprinklerall parts of which are quickly and readily disassembled, facilitatingthe convenient cleaning or replacement of parts.

A still further aim of the present invention is to provide a lawnsprinkler that is simple and practical in construction, strong andreliable in use, neat and attractive in appearance, relativelyinexpensive to manufacture, and otherwise well adapted for the purposesfor which the same is intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout, and in which:

Figure 1 is a perspective view of the present lawn sprinkler; and

Figure 2 is a side elevational view of Figure 1, and with parts of thedevice broken away and shown in section.

Referring now to the drawings in detail, wherein, for the purpose ofillustration, there is disclosed a preferred embodiment of the presentinvention, the numeral I represents a substantially U-shaped stand orframe generally comprising a pair of spaced parallel bearing legs I2.The web portion of the stand is bent upwardly to form a horizontallydisposed pivot portion I4 and downwardly and outwardly inclined sideportions I6.

Pivotally mounted en the pivot portion I4 is a bearing member or blockI8 having an integral, internally threaded hose engaging nipple 2 8 atone end.

A threaded bore 22 is provided in the block I8 and adjustably receivesthe threaded shank portion 24 of an eye member 2:6 that may be adjustedfor selective pivotal positions of the block I8 relative to the pivotportion I4.

Removably engaging an internally threaded recess 28 in the upper end ofthe block I8 is the reduced threaded end 30 of a spacer member 34.

The numeral 36 represents a cylinder or tubuaclaims. (c1. a99- 19)l 2lar body that isprovided with an integral closure 38 at its outer end.The inner end 40 of this body`36 is externally threaded to removablyengage a threaded socket 42 at the outer end of the spacer member 34.

A group ofrsucce'ssively spaced axially and radially displaced outletapertures 44 are provided in the surface of body 36 and are selectivelyopposed. by the annular anged portion46 of a resilient cup-like piston48 that is workable in the body. Disposed on opposite sides of thepiston 48 is a, pair of wearing plates 50 that are swivelled, as at 52,together with the piston on the inner end of a screw-threaded rod 54that is adjustably mounted in the closure 38.

Removably secured to the outer end of the rod 54, by the use of a screwor the like 56, is a knurled iinger-receiving disk 58 that may beemployed for selective adjustment of the piston within the body 36.

A group of apertures 44 include four equal and separate sides of theybody 36 and are referred to more specifically by the numerals 60, 62,64 and 66.

In practical use of the device, a water hose is connected to the nipple20, so that uid conducted by the hose will enter an inlet bore 6B in theblock I8, pass into the inlet bore l0 provided in the spacer member 34,and hence will enter the body 36. If it is desirable to eject Water fromthe body 36 on only one side, namely, from the series of apertures 60.the rod 54 is adjusted so that the lower edges of the ange 46 will beadjacent the upper aperture of the series 60. For ejecting water fromtwo sides of the body to circumscribe a half circle, the piston isadjusted so that the lower extremities of its flange 46 are disposedadjacent the upper extremity of the series` of apertures 62, and fluidwill be discharged from the series of apertures 60 and 62.

Obviously, by similarly adjusting the piston to the upper aperture ofthe series 64. fluid will be ejected from the body on three sidesthereof, and by raising the piston to bear adjacent closure 38. fluidwill be sprayed from all sides of the body.

In view of the foregoing description taken in conjunction with theaccompanying drawings, it is believed that a clear understanding of vthedevice will be quite apparent to those skilled. in this art. A moredetailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shownand described a preferred embodiment of the invention, the same issusceptible to certain changes fully comprehended by the spirit of theinvention as herein described and within the scope of the appendedclaims.

Having described the invention, what is claimed as new is:

1. A lawn sprinkler comprising a stand, a hose receiving memberpivotally mounted on said stand, means for adjusting said member atselected pivotal positions relative to said stand, a spacer elementremovably carried by said member and disposed perpendicularly thereto,an inlet bore provided in said hose receiving member, a

further'inlet bore provided in said spacer ele- A ment communicatingwith said first-mentioned bore at right angles thereto, a tubular bodyremovablyv carried by and eoplanar with said spacer element, a group ofsuccessively spaced axially and radially displaced apertures upon thesurface of the'body, aipiston slidably mounted in said body andincluding 'a flanged portion bearing against the inner periphery of saidbody'for uncovering some of said apertures on one side of said body, andmeans for selectively adjusting said piston within said body.

2. The combination of claim l wherein said means Vfor adjusting saidpiston within said head includes an adjustable .rod carried by said bodyand operatively connected to said piston.

3. The combination of claim 2 wherein said rod is swiveled to saidpiston.

4. A lawn sprinkler comprising a tubular body having a threaded openingat one end, a fluid inlet at the opposite end of said body, a pluralityof successively spaced axially and radially displaced apertures upon thesurface of the body. a piston having a resilient flanged portionreceived in said body for uncovering some of the apertures, a rodthreaded in said opening, means swivelling said rod to said piston, andfinger-receiving means for actuating said rod, said piston shieldingsaid rod from liquid in said body and the resilient flanged portion ofsaid piston bear- 'Ning against the inner periphery of said body.
